Answer:14/21
Step-by-step explanation: First find the LCM of the two denominators; LCM of 3 and 7 is 21. Next, find the equivalent fraction of both fractional numbers with denominator 21. For the first fraction, since 3 times 7 equals 21, 2/3= 2 times 7/ 3 times 7=14/21. Likewise, for the second fraction since 7 times 3=21, 1/7=1 times 3/7 times 3= 3/21 since the denominators are now the same, the fraction with the bigger numerator is the greater fraction.
